Hi Michael, Yaroslav,

I think that second command syntax only works for "git svn init" right now, not sure if it ever worked with "clone".

Any chance I could get that URL? (I probably won't get a chance to spend time debugging this until Friday). Might be worth it to get an strace or tcpdump to see what exactly is going on. Or at least some print statements around Git::SVN::Ra::new()...

It looks like support for specifying absolute URLs with "clone" has been broken for a while. Guess I'll need test cases...

Odd that the svnr one doesn't work.  Does changing:
         tags = /*:refs/remotes/tags/*
to:
         tags = *:refs/remotes/tags/*
help at all?

Minimizing should be the default in 1.6.5. I'm a bit stumped, too :x I'd like to see what network traffic git svn is sending for the "svnr" case vs "svn ls http://domain.com/project/releases"
